STM32L412 and reference voltage buffer
STM32L412xx datasheet DS12469 even in Rev. 8 talks about � Accurate 2.5 V or 2.048 V reference voltage buffered outputon the front page. The reference manual gives only availability on L43 and L45.
Resolved! Using DMA with UART on STM32H753ZI and getting HAL_DMA_ERROR_TE (Transmission Error)
Hello, I am trying to set the UART5 TX with the DMA. I am using Cube, and in the GUI I selected UART5 to asynchronous, and added DMA for UART5_TX. Then, in the generated code, I added this part as I didn't see initialization for the DMA (inside the M...
Compiler Errors, what is best practice to write code (when if(1==1) is false) )
Hello,Many times i get into problems that I should not get into, like simple logical mistakes while executing code:examples:uint32_t a = 1; if(a==1) { MCU goes here, it's how it should be; } else { MCU goes also here , how is this possible?; }M...
Powering STM32 L476RG at 1.8V - Any major disadvantages?
I'm currently using the STM32 L476RG for an application where I need to communicate with peripherals through SPI at 1.8V. Currently I'm using the TXB0108 bidirectional logic level shifter to convert my SPI lines from 3.3V to 1.8V but there are proble...
Corrupted data via SPI_HAL_Receive in STM32F407
Dear friends, I need your help with the issue of data corruption when reading the data on SPI bus in STM32F407. I'm using 24 channels of temperature measurement (slaves) with one master STM32F407. 12 channels are connected to SPI1, other 12 channels ...
Resolved! Could use some help getting a UART working in interrupt mode on a Nucleo H7A3ZI-Q
I've had some success getting UARTs to work on a Nucleo 413ZH board but am struggling to get the same code working on a Nucleo H7A3ZI-Q board. I have a logic analyzer connected to the TX and RX pins on the Nucleo boards. The HAL_UART_Transmit line (l...
Code alters a variable on itself
Hello,I want to be able to do multiple routines in my stm32 code. I went for the option to use Switch case statements. The problem is after the code has done one iteration the variable that is used in the switch statement(routine_test) changes on its...
USART blocked by Overrun error on my STM32L051
Hi everyone,I have a broblem regarding USART in overrun occurrence.In effect the "HAL_UART_IRQHandler" routine is called every incoming char, but this never calls callback routine (SYS_UART_RxCpltCallback).In debug mode I can see there is an USART_IS...
Creating .hex file from two banks memory of STM32H753
Hello,I have a problem with my .HEX file generated with KEIL 5.In STM32H753 there are two banks memory:FIRST BANK MEMORY : 0x08000000-0x080FFFFFSECOND BANK MEMORY : 0x08100000-0x081FFFFFMy project has this structure:0x08000000-0x08060000=> My own Boo...
